Title: Caseade Run Length Encoding
Inventor: CORPORATION XEROX
IPC: G06T9/00
Filed: 1967-09-28
Abstract: 1,190,067. Digital facsimile transmission systems. XEROX CORP. 28 Sept., 1967 [3 Oct., 1966 (4)], No. 44135/67. Headings H4F and H4P. The time-bandwidth product of binary signals, e.g. facsimile signals, is reduced at a transmitter by run-length encoding, the signals being coded into words the lengths of which depend on the statistical distribution of the runlengths of the data. The system is such that run lengths which occur frequently are represented by short words. At the transmitter, Fig. 1, binary data from scanner 101 is fed to a unit 103 comprising a shift register associated with circuitry which determines whether the length of a sequence of 0-bits is 1, 2, 3, or more than 3 bits long and feeds units 107, 105. The register output feeds unit 109. Unit 109 comprises a shift register/ counter, its output feeding a buffer store 119 and transmission unit 121. The stages of the register in 109 are monitored by units 107, 105. The bits from 103 are counted at 109 and when the counter contains a certain bit pattern the pattern is shifted one or more steps and, under control of units 105, 107, counting continues until another certain pattern is reached, whereupon the count is again shifted. Thus the generated code word length increases for each additional n 0-bits from 101, n varying with the run length. Run lengths consisting of 1-bits are encoded in a different code. The codes used for 0 and 1 bit runs are shown in Fig. 8 (not shown). Each run code transmitted is preceded by the code word for a run one bit long of 1 or 0 state as appropriate to the run. The receiver, Fig. 2, comprises an encoder 201 identical to that at the transmitter, driven by binary data on line 209. At the start of a run register 109 contains the code word of a one bit run in 1-bit or 0-bit code as appropriate (e.g. each line scan starts with one or more 0-bits) and register 203 is filled by a like number of bits from input buffer 213. If the registers do not contain the same words, gate 205 detects the inequality and drives unit 207 to print a 1 or 0 bit as appropriate at printer 215. The bit from 207 also drives encoder 201 so that register 109 now shows the second code word of the appropriate 1- or 0-bit code. If there is still inequality a second bit is printed, the encoder stepped and the cycle repeated. Hence register 109 exhibits successively the successive words of the appropriate 1 or 0 code-register 109 being shifted after every n bits, as at the transmitter, and such shifting causing corresponding shift in register 203-until gate 205 determines equality of the registers' contents. Unit 207 then causes printing of the other bit state and sets encoder 201 to encode according to the other code.

Title: Improvements in and relating to the transmission and reception of signals representative of television and sound
Inventor: LORD ARTHUR VALENTINE

Filed: 1965-10-22
Abstract: 1,093,093. Multiplex pulse signalling; television. BRITISH BROADCASTING CORPORATION. Sept. 30, 1966 [Oct. 22, 1965], No. 44902/65. Headings H4F and H4L. A television transmitter which is arranged to transmit a carrier oscillation modulated by vision signals separated by intervals during which synchronizing signals are present, includes means for changing the frequency of the carrier oscillation during the said intervals, and means for modulating the carrier of changed frequency by signals representing sound or other auxiliary signals accompanying the vision signals. Fig. 2 shows the response of a receiver for a typical negatively modulated vision signal, the carrier frequency being changed, either by frequencyshift or by switching to a different oscillator, from a frequency f v  to a frequency f v , + #f during the synchronizing pulse intervals. The effect of this is to increase the receiver sensitivity during these intervals. Also, with a monochrome signal the transmitter may be modulated in amplitude only with the vision signal, the frequency-shift being sufficient to define the synchronizing pulses. The carrier of changed frequency may be frequency, phase or amplitude-modulated by the sound or other signals. As described, the transmitter, Fig. 6 (not shown) includes a sampler for the sound signals which is controlled by the sync. pulses, the resulting amplitude-modulated pulses frequency-modulating the carrier of changed frequency. Means may be included to compensate for any demodulation at the receiver due to the receiver amplitude/frequency characteristic (e.g. vestigial shaping). At the receiver, Fig. 7, the vision signals are fed to a cathoderay tube via conventional circuits 18, 19 and an I.F. signal corresponding to f v  + #f is supplied via an electronic switch 23 controlled by the sync. pulses to a limiter and discriminator 24. The leading edge of each audio sample may be distorted due to the fact that the signal is received as bursts of carrier and the effect of this is minimized by a narrow pulse sampler 25 controlled by the sync. pulses, the resulting narrow pulses being supplied via a low-pass filter to the A.F. output. If the frequencies f v  and f v  + #f are generated separately and f v  is not completely suppressed during sync.- pulse intervals, " intercarrier " techniques may be used.

IPC: D04B15/68
Filed: 1962-12-06
Abstract: A multifeed circular knitting machine has a bolt cam (10), Fig 2, not shown, associated with each feeding station which determines whether the needles are engaged by the usual tucking, clearing and knitting cams or pass through the station at a low level.  To enable such selection to be made all of the needles are identical being provided with butts of equal length.  In addition a pivotable jack (4) Fig. 1, not shown, is positioned beneath each needle and is provided with high and low butts (12, 11) such that whether the jack is pivoted in one position or another determines whether the butt (12 or 11) is operative to engage cams (13) at each station at levels (d or e.) The cams (13) are movable up and down to determine whether the jack and consequently the needle is raised at that position so that when the cam (10) is inoperative, operation of the needle is determined by the jack (4).  The position of the jacks (4) is determined by a series of selectors slidable horizontally to engage butts (24) on the jacks and pivot their upper ends inwardly.  To permit the selection, a locking jack (5) is first lowered so that a tail portion (19) of the jack (4) is free to move whereafter all of the jacks are then deflected by a cam (21) to pivot the upper end of the jacks outwardly for engagement or otherwise by the selectors.  After selection, the locking jack (5) is raised so that its portion (18) engages the jack (4) on one side or the other of its tail portion (19) so locking the jack (4) in position to cause the butts (12 or 11) to be operative with their associated cams.
